CABLE-G RIP.

SPECIFICATION forming part of Letters Patent No. 674,708, dated May 21,1901.

Application led November 24:, 1900. Serial No. 87,627. (No model.)

To all whom it may concern:

Be it known that I, CHARLES NOBLE, a citizen of Nova Scotia, and aresident of Sisson, in the county of Siskiyou and State of California,have invented a new and Improved Cable-Grip, of which the following is afull, clear, and exact description.

This invention relates to improvements in cable-grips, and moreparticularly to, cables employed in hauling logs or timber; and theobject is to provide a grip having but few parts and not liable to getout of order and so constructed that the simple act of hooking it over acable after the draw-dogs are fixed in a log causes it to clasp or gripthe cable and remain fixed thereon until the draw-dogs are removed orsomething breaks other than the grip.

I will describe a cable-grip embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar'characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side View of a grip embodying my invention engaged with acable and gripping therewith. Fig. 2 is a partial section and partialelevation showing the grip as released, and Fig. 3 is a section on theline 3 3 of Fig. 1.

The grip comprises two side plates 5 and 6, secured together at the endsby bolts or rivets, there beingaspace between the two side plates. Theside plate 5 extends downward and has a hook portion '7, designed togrip with one side of a cable and designed to engage with the oppositeside of the cable is a jaw 8, movable between the plates 5 and 6, therebeing sufcient space between the two side plates for the free movementof said jaw. The two side plates have upward extensions 9 and 10,between which a cam-lever 11 is pivoted, the cam-shaped lower end ofthis lever being designed to engage with the upper edge of the movablejaw 8. A link 12 extends from the upper end of the cam-lever andconnects with a ring or link 13, which also connects by means of a link14 with a rearward extension 15 from the side plate 5, this link 14being designed to slide upon said extension.

In operation all that is required is to en-A gage the jaws with thecable, as indicated in Fig. 2, and engage the chains extended from thelog or from the dogs engaging with the log with the ring 13. The motionof the cable in the direction indicated by the arrow adjacent theretodraws the grip forward, and the strain on the ring 13 in the directionof the arrow crossing the same draws the cam-lever 11 rearward andforces the movable jaw 8 down upon the cable, and it is obvious that thegreater the strain on the ring 13 the greater will be the pressure ofthe jaw 8 upon the cable. As the ring 13 is drawn backward the link 14slides along the bar or projection 15, thus holding the ring 13 at itsstrongest point of tension and keeping the grip tightly closed on thecable even when logs are being drawn downhill. To release the grip, allthat is required is to knock out the draw-dogs from the log, and thering 13 being thus released the pressure of the grip is relieved and itmay be readily removed from the cable.

It will be seen that this grip is practically vautomatic in itsoperation-that is, there are no-levers designed to be operated manuallyand there are no springs to be broken.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A cable-grip, comprising side plates, a jawconnected to one of said side plates, a jaw movable between the sideplates, a camlever pivoted between the side plates and adapted forengagement with the movable jaw, a bar extended from one of the sideplates, and link connections between the lever and said bar and slidablelengthwise of said bar, one of said links being adapted for connectionwith a drawchain or the like, substantially as specified.

2. A cable-grip, comprising side plates, a jaw fixed to one of said sideplates, a jaw movable between the side plates, a cam-lever pivotedbetween the side plates and adapted for engagement with the movable jaw,an extension from one of the side plates, a. ring name to thisspecification in the presence of adapted for connection with edraw-chain or two subscribing witnesses.
